常熟周大辅鸽峰草堂抄书补考

2015年,郑伟章先生发表《常熟周大辅鸽峰草堂钞书藏书知见录》一文,搜集常熟周大辅鸽峰草堂抄校本67种,藏本29种,凡96种。今检中国科学院图书馆藏周氏鸽峰草堂抄本13种,皆未见郑氏著录,甚至不见于《中国古籍总目》。这些抄本据以抄录、校勘的底本大多源自藏书名家,如惠氏红豆斋、丁氏八千卷楼、劳氏丹铅精舍、刘氏味经书屋、瞿氏清吟阁等等,且书中皆有周大辅校勘记,朱笔钩改,浮签甚多。故不瑞陋,略加考论,续貂于此。

基于Rocky DEM的松散润叶筒内抄板作用的模拟与优化

为深入研究松散润叶筒内叶片在抄板上的掉落过程,提升叶片的耐加工性,利用三维建模软件建立松散润叶筒三维模型,通过Rocky 2021 R2离散元仿真软件创建薄片柔性叶片进行数值模拟,对叶片在松散润叶筒内抄板上的运动进行可视化计算。根据抄板上叶片的持料量百分比曲线和落料速率曲线,将叶片的掉落过程分为两个阶段。结果表明:片状颗粒的受力区别于刚性球体间的点对点接触受力,叶片形状不可忽略;松散润叶筒转速为15 r/min时,叶片在筒体底部分布较少,筒体上半部分分布较多;抄板安装角度为80°时,板上持料量增多,抄板倾角较合理,增温增湿效果最优;松散润叶筒倾角对叶片在抄板上掉落的轴向速度影响显著。通过仿真得出叶片在抄板上掉落过程的优化参数,有助于松散润叶过程调控,指导实际工业生产。

从“四部”到“四分”——佛教律抄在唐代的发展

《毗尼心》《四分律小抄》《略抄》《杂抄》等佛教律抄文本在唐代相继问世。这些文本较六朝时期的律抄有新的发展。首先,在思想上,从早期“会通诸律”的“四部律抄”发展为独尊《四分律》的“四分律抄”;其次,受佛教注疏传统的影响,律抄在文本形式上呈现“事数化”“条目化”的特点。唐代道宣《四分律删繁补阙行事钞》也是受六朝律抄深刻影响的作品。唐代的这些律抄文献反映了中古“律疏”与“律抄”两大传统的融合,向我们展示了印度佛教律仪向中国佛教戒律实践过渡的一个面向。

Probabilistic analysis of tunnel face seismic stability in layered rock masses using Polynomial Chaos Kriging metamodel

Face stability is an essential issue in tunnel design and construction.Layered rock masses are typical and ubiquitous;uncertainties in rock properties always exist.In view of this,a comprehensive method,which combines the Upper bound Limit analysis of Tunnel face stability,the Polynomial Chaos Kriging,the Monte-Carlo Simulation and Analysis of Covariance method(ULT-PCK-MA),is proposed to investigate the seismic stability of tunnel faces.A two-dimensional analytical model of ULT is developed to evaluate the virtual support force based on the upper bound limit analysis.An efficient probabilistic analysis method PCK-MA based on the adaptive Polynomial Chaos Kriging metamodel is then implemented to investigate the parameter uncertainty effects.Ten input parameters,including geological strength indices,uniaxial compressive strengths and constants for three rock formations,and the horizontal seismic coefficients,are treated as random variables.The effects of these parameter uncertainties on the failure probability and sensitivity indices are discussed.In addition,the effects of weak layer position,the middle layer thickness and quality,the tunnel diameter,the parameters correlation,and the seismic loadings are investigated,respectively.The results show that the layer distributions significantly influence the tunnel face probabilistic stability,particularly when the weak rock is present in the bottom layer.The efficiency of the proposed ULT-PCK-MA is validated,which is expected to facilitate the engineering design and construction.

Suppression and synchronization of chaos in uncertain time-delay physical system

The mechanical horizontal platform(MHP)system exhibits a rich chaotic behavior.The chaotic MHP system has applications in the earthquake and offshore industries.This article proposes a robust adaptive continuous control(RACC)algorithm.It investigates the control and synchronization of chaos in the uncertain MHP system with time-delay in the presence of unknown state-dependent and time-dependent disturbances.The closed-loop system contains most of the nonlinear terms that enhance the complexity of the dynamical system;it improves the efficiency of the closed-loop.The proposed RACC approach(a)accomplishes faster convergence of the perturbed state variables(synchronization errors)to the desired steady-state,(b)eradicates the effect of unknown state-dependent and time-dependent disturbances,and(c)suppresses undesirable chattering in the feedback control inputs.This paper describes a detailed closed-loop stability analysis based on the Lyapunov-Krasovskii functional theory and Lyapunov stability technique.It provides parameter adaptation laws that confirm the convergence of the uncertain parameters to some constant values.The computer simulation results endorse the theoretical findings and provide a comparative performance.

A novel variable-order fractional chaotic map and its dynamics

In recent years,fractional-order chaotic maps have been paid more attention in publications because of the memory effect.This paper presents a novel variable-order fractional sine map(VFSM)based on the discrete fractional calculus.Specially,the order is defined as an iterative function that incorporates the current state of the system.By analyzing phase diagrams,time sequences,bifurcations,Lyapunov exponents and fuzzy entropy complexity,the dynamics of the proposed map are investigated comparing with the constant-order fractional sine map.The results reveal that the variable order has a good effect on improving the chaotic performance,and it enlarges the range of available parameter values as well as reduces non-chaotic windows.Multiple coexisting attractors also enrich the dynamics of VFSM and prove its sensitivity to initial values.Moreover,the sequence generated by the proposed map passes the statistical test for pseudorandom number and shows strong robustness to parameter estimation,which proves the potential applications in the field of information security.

On fractional discrete financial system:Bifurcation,chaos,and control

The dynamic analysis of financial systems is a developing field that combines mathematics and economics to understand and explain fluctuations in financial markets.This paper introduces a new three-dimensional(3D)fractional financial map and we dissect its nonlinear dynamics system under commensurate and incommensurate orders.As such,we evaluate when the equilibrium points are stable or unstable at various fractional orders.We use many numerical methods,phase plots in 2D and 3D projections,bifurcation diagrams and the maximum Lyapunov exponent.These techniques reveal that financial maps exhibit chaotic attractor behavior.This study is grounded on the Caputo-like discrete operator,which is specifically influenced by the variance of the commensurate and incommensurate orders.Furthermore,we confirm the presence and measure the complexity of chaos in financial maps by the 0-1 test and the approximate entropy algorithm.Additionally,we offer nonlinear-type controllers to stabilize the fractional financial map.The numerical results of this study are obtained using MATLAB.

说“抄手”

作为小吃名称的“抄手”,属于词义引申的结果,其原义是行为,引申义是具有行为姿态特征的事物。其词义隐晦的主要原因是引申方式不符合常规,其语素义不是来自“抄”的基本义,并且词语本身具有多个义项。同时,围绕“抄”字的词义演变梳理其核心义,可以发现,“抄”由本义“用以叉取的金属器具”引申为“叉取”这一动作义,接着由“叉取”通过隐喻的途径引申为“抢劫、强取”“誊写”“舀取”等义,然后这三个义项又通过隐喻或者转喻引申出其他意义。在这一基础上,分别探求了动词“抄手”和名词“抄手”的词汇化过程。从近代时期至现代时期,动词“抄手”的词义发生了转移。在现代汉语“抄手”的不同义项中,表小吃义为绝对高频用法。

Multi-Level Image Segmentation Combining Chaotic Initialized Chimp Optimization Algorithm and Cauchy Mutation

To enhance the diversity and distribution uniformity of initial population,as well as to avoid local extrema in the Chimp Optimization Algorithm(CHOA),this paper improves the CHOA based on chaos initialization and Cauchy mutation.First,Sin chaos is introduced to improve the random population initialization scheme of the CHOA,which not only guarantees the diversity of the population,but also enhances the distribution uniformity of the initial population.Next,Cauchy mutation is added to optimize the global search ability of the CHOA in the process of position(threshold)updating to avoid the CHOA falling into local optima.Finally,an improved CHOA was formed through the combination of chaos initialization and Cauchy mutation(CICMCHOA),then taking fuzzy Kapur as the objective function,this paper applied CICMCHOA to natural and medical image segmentation,and compared it with four algorithms,including the improved Satin Bowerbird optimizer(ISBO),Cuckoo Search(ICS),etc.The experimental results deriving from visual and specific indicators demonstrate that CICMCHOA delivers superior segmentation effects in image segmentation.

Can spatial planning in the Polish Carpathians be enforced? How spatial chaos indicators depict a gap between scientific knowledge and practice

Despite their strategic hydrological importance for neighbouring areas,the Polish Carpathians are experiencing spatial chaos,which may weaken their adaptability to the progressive climate change.The article attempts to answer the question of whether spatial planning,which is supposed to guarantee spatial order,fulfils its role and whether the knowledge of the natural conditions of spatial development is respected in the spatial planning process.Using GIS techniques,up to 238 communes were analysed in terms of their spatial coverage,the degree of scattered settlement,and the violation of natural barriers by location of buildings in areas that are threatened with mass movements or floods;by settlement on excessively inclined slopes and in areas with adverse climatic conditions.Spearman non-parametric rank correlation analysis and the multidimensional Principal Component Analysis(PCA)technique were performed to investigate relations between spatial chaos indicators and the planning situation.The analysis of the data has revealed that spatial planning does not fulfil its role.Serious errors in location of buildings have been noted even though the communes are covered by local spatial development plans.Scientific knowledge is not sufficiently transferred into planning documents,and bottom-up initiatives cannot replace systemic solutions.There is a need for strengthening the role of environmental studies documents in the spatial planning system.This would facilitate the transfer of scientific knowledge into the planning process and help to protect mountain areas.The development of a special spatial strategy for the Polish Carpathians in compliance with the Carpathian Convention is also recommended.
